My first 20g tank only lasted 6 months, kid sister-in-law poured about 1/4 cup of fish food and hid. not too long before the ammonia spikes and kills all the fish. And a reason to upgrade.
After 2 months of planning and saving I am now cycling my 50g DT with 20g Sump. I'm using Jebo Quadplex for my skimmer with seaquest 1600 and seaquest 2200 return. I'm not hooking up my 3w wave maker because I'm planning to buy a 6w version. I'm currently doing alot of DIY, to save some cash.
